I've bought/ordered everything for my aftermarket sub install into my 2008 IS250 with the exception of a line output converter. Based on previous threads/google I was planning on going with the AudioControl LC2i. I have Mark Levinson so I was going to tap the positive/negative wires for my sub and am really trying to figure out which other speaker to tap into, it seems most use the front mid.

Could someone please confirm if this is the best option or recommend a better option (LOC/speakers to tap)

 

I'm using the LC2i in my setup with the factory non-ML non-NAV system. Unfortunately I had it wired in by a Future Shop tech, so I couldn't tell you what he tapped into, but I can take a pic if that would help.

Also I LOVE how the system sounds now.

 

Sub inputs for the subs, obviously. But exactly what aftermarket speakers are you putting into the car and installing them where?

 

If its not too much trouble a picture could be helpful. But from what I've read non-ML has 4 stock sub wires (2 positive and 2 negative) so I'm guessing thats how your LC2i is hooked up.

I'm only adding 1 subwoofer, no other speakers. The LC2i has 2 inputs, obviously one will be the +/- from the stock sub. I'm trying to figure out what people used for the second input.

 

I'm not familiar enough with the stock system in these models, but I'd assume you can use a single - and a single + wire for your aftermarket setup for the signal. Are the stock subs dual voice coil? Is that the reason for both sets of - and + wires?
